DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 742,741, dated October27,

Application filed August 18, 1903. Serial No. 169,919. (No model.)

To all, whom it may concern:

Be it known that I, MILLARD F. RICHARD- SON, a citizen of the UnitedStates, residing at Holton, in the county of Jackson and State ofKansas, have invented a new and useful Draft-Equalizer, of which thefollowing is a specification.

This invention relates to draft-equalizers; and one of the primaryobjects thereof is to provide an efficient means for equalizing the pullon different sides of the draft-pole, so as to compensate for thedifference in the horsepower.

Another object of the invention is to provide means for efficientlyassembling the parts, and, further, to provide a device of the classdescribed which will be cheap, durable, and which will readily performthe service for which it was intended.

Other objects andadvantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims, it being understoodthat changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

In the drawings, Figure l is a top plan view of the equalizer, showingone position of the parts. Fig. 2 is a similar view showing aslightly-modified position. Fig. 3 is a detail perspective view of oneof the links, and Fig.

4 is a detail perspective view of one of the levers.

The reference-numeral 1 designates the front hounds,carrying the tongues2 and supported by the axle 3, all of common construction.

The draft-equalizer is supported by the parts just described, and it isillustrated as having a long lever 4: transversely disposed withrelation to the pole and terminally pivoted, as at 5, to. an arm 6,rigid on the axle 3. This lever we term the primary equalizinglever,mainly on one side of the pole, the length of the longest arm 7 beinggoverned by the ratio of the horse-power on the respective sides of .thepole. A lever 8 of the first order is fulcrumed in rear of theprimarylever, and one end of said lever 8 is connected to the long armof the of the lever 8 being connected to swingletreesupporting lever 9by a link 10, illustrated as being in the form of a loop and straddlingthe lever 4. 9 is a lever of the second order and is fulcrumed to thetongue, from which leads a brace 11, supported from the hounds by abrace 12. This brace 11 constitutes a bracket terminally supporting anindependently-pivoted lever 13, which terminally supports a doubletree14 by a connection 15. This lever 13 carries a roller 16, adapted tocontact with and roll upon the edge of the lever 4. when resistance isoffered to one draft device by the other. When the pull is properlyproportioned, the roller will drop into the seat or notch 17, providedin the lever 4; but when an unequal pull is offered on either side ofthe pole 2 the roller will be unseated. As before stated, the proportionof the relative ends of the lever 4 on either side of the pole will becalculated accordingly as the previously-designed oppositely-locatedhorse-powers are to be employed.

t is unsupported with respect to the pole, being fulcrumed at a pointdistant from the pole, so that considerable leverage will be had at theterminal of the longer or free arm thereof. It will also be observedthat the limit of movement is governed by the guideloop 20, carried bythe hounds. This loop may or may not be employed, as desired, although Iprefer to apply it as shown.

I claim .1. The combination with a draft-pole, of a primaryequalizing-lever mainly on one side of the pole and fulcrumed at a pointdistant from the pole, a lever of the first order connected to theprimary equalizing -lever, a swingletree-support connected to the leverof the first order, and a-whifiietree-supporting lever, independentlymounted and removably engaging the primary equalizing-lever.

2. The combination with a draft-pole, of a long equalizing-levertransversely disposed with relation to the pole, and independentlypivoted at a point distant from said pole, a draft device, connected tothe lever to exere lever 4, the other end 7 cise a pull in onedirection, and means for resisting the pull on the lever, comprislng alever removably engaging said equalizing-lever, and draft meansconnected to the lever.

3. In a draft-equalizer, the combination of a plurality of levers, and acooperating draft device, one of said levers having a notch, and anindependentlymounted lever, for supporting a draft device and removablyengaging the notch.

4. In a draft-equalizer, the combination of a plurality of levers, oneof which is provided with a notch, and an independentlvmounted lever,removably engaging the notch.

5. In a draft-equalizer, the combination with a vehic1e-pole,of a leverextending across the pole and terminally fulcrnmed independentlythereof, a second lever, having, one end intermediately connected to thefirst lever, a lever pivoted to the pole, and connected to the remainingend of the second lever, and

an opposing lever oppositely engaging the first-named lever.

6. In adraft-equalizer, asystem of connected levers one of which isterminally supported and provided with a free end, and an
